Eliminating FV from the SCCA Ranks/Rain Light
#34719 from Stevan Davis · Not recommended · Minutes (2023-11 Fastrack)
Thank you for your letter. While the rain lights from Lifeline and Cartek that meet FIA Standard 8874-2019, Technical List No. 76,
do list a 700 mA current draw, the existing standard of a "15-watt bulb" that many competitors still use represents a current
draw of 1250 mA. The 700 mA is therefore a significant reduction in current draw in comparison. Other peripheral items such as
data collection, video, and communication devices that competitors have added and have become accustomed to are not
directly related to the analysis, because the FV rules permit the use of secondary batteries "to run video cameras/recorders,
communications equipment and/or gauges and data acquisition systems." See GCR section 9.1.1.C.11.B. This provision was
adopted several years ago to support the addition of such additional peripheral power draws specifically because FVs run total
loss electrical systems. In considering the new F/SR rain light rule for 2024, a number of videos from SCCA races were reviewed

as were direct comments from competitors and, with safety being paramount, the FIA 2019 standard was ultimately selected,
because it was believed to be a well researched and well thought-out standard based on the rigors of open wheel and sports
prototype racing. Cost was a concern as was an understanding that many competitors are still running the older lights, meaning
that a significant number of people will need to upgrade to a brighter rain light. However, a quick Internet search shows that the
Cartek rain light that meets the SCCA 2024 F/SR rain light rule can be found for as low as $168 shipped, while the referenced
Afterburner rain light that does not meet the FIA 2019 standard can be found for $110 shipped. Others’ experiences may vary.
The bottom line is that the decision to go to the FIA 2019 standard was based on safety concerns and consistency in what fellow
competitors are able to see, and the $58 difference in cost for what is likely a one-time purchase does not seem excessive in that
regard. While low-cost LED truck and trailer lights may appear to be bright, they may not have a sufficient brightness level when
viewed at an angle, which is an important factor when racing in close quarters. Again, adopting the FIA 2019 standard covers this
concern.
